World Series of Fighting has added three new preliminary fights to its upcoming sixth event.

The WSOF 6 undercard streams live on Sherdog.com prior to the show’s NBC Sports Network main card broadcast and will see UFC veteran Jacob Volkmann collide with Pride veteran Luiz “Buscape” Firmino. Twelve-year pro Fabio Mello will also compete against unbeaten Nick LoBosco, while Alexandre Pimentel takes on Jade Porter. The Oct. 26 event takes place at Bank United Center in Coral Gables, Fla., and is headlined by a welterweight title showdown between Josh Burkman and Steve Carl.
